Shamans have two forms of resurrection, Ancestral Spirit which is gained at level 12 and it works just like the redemption or resurrection but shamans have the ability to revive themselves with Reincarnation.

Druids have rebirth, a resurrection spell that is different from all others because it can be cast while still in combat with a 2 second cast and using a reagent, but with a 30 minute cooldown time sometimes it can be difficult to know when to use it and who to use it on.
